- = separates axle groups and/or different axle functions (6x4-2 is 6x6 with undriven rear axle) Basis is always the standard configuration, meaning a steered front axle and a non-steered driven rear axle. This means: If only the front wheels are steered, the rearmost part of the formula can be left out.
The standard rail weight for British railways is now 113 lb/yd (56.1 kg/m). Before the 1990s, most diesel locomotives were built to a maximum axle load of 19 long tons (19.3 tonnes; 21.3 short tons) so the maximum locomotive weight was 76 long tons (77.2 tonnes; 85.1 short tons) for a four-axle locomotive and 114 long tons (115.8 tonnes; 127.7 short tons) for a six-axle one.
Four powered axles, connected by driving rods or gears, all mounted in the locomotive's frame (Whyte notation: 0-8-0). 1′D1′ One leading idle (non-driven) axle mounted in a bogie, four driven axles mounted in the frame and connected by driving rods or gears, followed by one trailing idle axle mounted in a bogie (Whyte notation: 2-8-2).

Each standard tracked vehicle is also defined in terms of track width, length, and spacing. Standard wheeled vehicles are designated by the same MLC numbers (4 through 150), which correspond to about 85% of the gross weight in short tons. Each standard wheeled vehicle is defined in terms of gross weight, number of axles, axle spacing, and axle ...
In this case, yielding occurs when the equivalent stress, , reaches the yield strength of the material in simple tension, . As an example, the stress state of a steel beam in compression differs from the stress state of a steel axle under torsion, even if both specimens are of the same material.
As high-speed electric locomotives in the 1980s began to achieve powers in the 6,000 hp range, new Co-Co designs appeared, as more axles were needed to distribute this high power. The BR class 92 was a predominantly freight locomotive of this arrangement for the Channel Tunnel , although the passenger Eurotunnel Class 9 instead use a Bo-Bo-Bo ...
